Ferdinand Schorbach from Hanover planned the building, which was executed by the architects Kreizner and Hatzmann.

Contrary to the usual practice of building symmetrically and in classical forms, the Solmsschlösschen was built on an irregular floor plan, which resulted from the size and function of the individual rooms. Designed as a building group, wing buildings, corner towers and bays form around the tower-like main structure.

From the middle of the 18th century, half-timbering was still frowned upon as a poor man's construction method and was therefore often concealed under plaster. The fact that a member of the high nobility chose this building material for his residence led to imitators - half-timbering was increasingly used for the upper floors.
